I've just bought some Kong paste and an extra Kong for Mitzi 'cos I'm going to try filling the new Kong with the paste then freezing it to see how she gets on with it... see if it'll keep her entertained for longer than room temperature Kong and paste!
I'm going to try making some home-made treats for her too and it'll only be 3 ingredients! Tuna in oil, wholemeal flour and eggs! We need to get a mixing bowl and spoon first though! lol
